The Canal Duplication Project in the Small Bitter Lakes is Ready for Actual Operation"
 
Admiral Ossama Rabiee, Chairman and Managing Director of the Suez Canal Authority, has announced the issuance of new navigational charts of the Canal after adding the updates of the southern sector development project, and their approval by the Egyptian Navy's Hydrographic Department (ENHD) and the British Admiralty, which is responsible for issuing electronic charts and navigational data of Egyptian ports and the Suez Canal. 


 
H.E., the Chairman, emphasized that all necessary measures have been completed to ensure that the transiting vessels have acquired the new charts.
Chambers of shipping have been notified, and the Canal’s charts have been amended in the Electronic Chart Display and Information System (ECDIS).
Additionally, navigational updates for paper charts have been issued until the new issue of printed charts for vessels are issued.


 
H.E. has also stated that the new navigational charts include the 40-meter widening towards the eastern bank within the scope of the Canal’s widening project from km 132 to km 162 (Canal marking) and adding the new doubled part, 10 km in length, from km 122 to km 132 (Canal marking) at the Small Bitter Lakes area, with the navigational aids located on them which ensures navigation safety in the Canal.


 
Adm. Rabiee has confirmed the technical validity of both parts of the Southern Sector Development Project, and the readiness of the Canal duplication project in the Small Bitter Lakes area for actual operations after the completion of all technical and navigational procedures including the installation of navigational aids, and the completion of training works for the Authority’s pilots on safe transiting through the southern sector at the Suez Canal Maritime Training and Simulation Academy.

The Chairman of Suez Canal Authority has highlighted that the southern sector development project is considered a quantum leap that will contribute to enhancing the competitiveness of the Canal and attracting new classes of ships and marine units that have not transited through the Canal before.
That is in addition to transiting safely and increasing the rates of navigational safety for unconventional transit operations.


 
Adm. Rabiee has also stressed the navigational and economic importance of the southern sector development project and its role in enhancing the Canal's leadership and raising its global classification with its multiple navigational advantages and most notably increasing the margin of navigational safety and reducing the impact of the pressure of the two banks of the Canal on vessels of a large draft after expanding the Canal 40 meters eastward, and increasing its depth from 66 feet to 72 feet within the Canal's expansion project.
 
Moreover, the Canal’s doubling project increases the accommodation capacity of the Canal by 6 to 8 vessels on a daily basis and adding 10 kilometers to the length of the New Suez Canal; reaching 82 km instead of 72 km.

A new layer in the GeoGarage platform : Argentina nautical charts based on rasterized ENC material from SHN

 Availability of a new dedicated layer for Argentina with SHN rasterized ENCs (full catalogue)
 
The layer also contains charts for Antarctica areas managed by SHN
so 6 ENC for : Coronation & Laurie Island, Esperanza, Primavera, Melchior, San Martin Bases & Deception Island
 
Until today, the GeoGarage platform used the raster paper chart material (RNC) provided by SHN to display nautical charts for the Argentina areas.

For internal management reasons specific to SHN (Serviceio de Hidrografia Naval) -the Argentina Hydrographic Office- has canceled the delivery of updated RNCs.
By the way, the availibility of RNCs was not completed (83 raster charts on a total of 144 paper maps).

The GeoGarage platform was already in the capacity to deliver a rasterized visualization of Electronic Navigation Chart (vector ENC) through their web services (WMTS) for their B2B customers involved in webmapping and other onshore GIS activities.

Today, the GeoGarage platform is now ready to propose the visualization of official ENC to their customers using mobile navigation apps (non SOLAS) so Weather 4D Routing and Navigation on iOS and SailGrib on Android.
 
In consequence, the GeoGarage platform no longer offers a subscription to Argentina Raster charts for Argentina on its e-commerce platform for mobile apps.
However, the Argentina RNC subscription will continue for their current mobile customers until its expiry date (visible on your W4D R&N/Sailgrib application) but will not be automatically renewed on this date.

The RNC plan is replaced by a new layer based on ENC type maps edited by the Servicio de Hidrografia Naval (SHN), and rasterized for W4D/Sailgrib : Argentina (derived from SHN ENC)
The price of the annual subscription is now 38.99 EUR.
 
So Weather4D R&N and Sailgrib users (with last updated versions) can right now display the whole catalogue of NLHO ENC (107 ENC at this time), with a half-yearly updating process : see GeoGarage news

Today, in this first version, the vector ENC are displayed using a graphical rendering similar to the one used in official ECDIS (s-52 IHO specifications) : they are not to be used for shipping navigation (IMO SOLAS), but only for recreative use, not as a primary tool for navigation.
Effectively, in contrast to the use in ECDIS, there is no possibility -today with the W4D/SailGrib current version- to ask for text info and details regarding any navigational objects (beacon, buoy, marks...).

Germany (BSH) layer update based on rasterized ENC in the GeoGarage platform

The first HD ENC maps covers the Rostock harbor waterways area.
DE6HOSR1 / DE6HOSR2 / DE6HOSR3
Depth contours are now not only shown in 2m, 5m or 10m, but every full meter.  
 
3 HD ENCs replacing DE6HOSRO

 -----------------------------------------------------------------------------------------------------------------------------
 
The Federal Maritime and Hydrographic Agency (BSH) is already presenting the High Density Electronical Navigational Chart - HD ENC for short - in order to make the electronic nautical chart more precise and standardised than ever before on the way to the introduction of the new international S100 standard in 2026
 
BSH has started producing new electronic nautical charts with a higher resolution for depth display
The main feature of the new HD-ENC charts is the much more detailed depth information in higher resolution and with depth contours at 1 metre intervals instead of the previous 5 metre intervals, which enables a higher degree of safety, particularly when navigating near the coast.

With these HDENCs, navigation can be improved because the available navigation space can be utilized much better.
This makes navigating German waters increasingly safe and we are making an active contribution.
BSH is now gradually rolling out production to ports and heavily frequented sea waters.

Imray to stop publishing paper charts

 
Imray layers in the GeoGarage platform
 
From Imray
 
"After more than 200 years of guiding mariners, Imray will begin phasing out its chart publishing operations, marking the end of an era.
This tough decision reflects the shift toward digital navigation, but we’re not going anywhere.
 
We’ll continue supporting sailors with our trusted pilot books, cruising guides, and the popular ‘Explore with Imray’ digital product.
Paper charts will be supported until the end of the 2025 season, so now’s the time to stock up.
We thank our incredible customers and partners for their loyalty. As we chart a new course, our mission to provide reliable navigation resources lives on. "
 
An opportunity for collectors and historians

The announcement of the end of paper map production also opens the door to the preservation of a historical legacy.
Imray is offering potential buyers the opportunity to take over its cartography business, or to acquire the rights to its name.
This approach could be of interest to maritime history enthusiasts, or those wishing to perpetuate the paper chart tradition in a more confidential or museum context.

For their part, traditional navigation enthusiasts and collectors will have the opportunity to acquire the latest editions of these emblematic charts, which have become rare and precious objects.

Blueback nautical charts began appearing in London in the late 18th century. 
Bluebacks, as they came to be called, were privately published large format nautical charts known for their distinctive blue paper backing.
The backing, a commonly available blue manila paper traditionally used by publishers to warp unbound pamphlets, was adopted as a practical way to reinforce the low-quality paper used by private chart publishers in an effort to cut costs.
The earliest known blueback charts include a 1760 chart issued by Mount and Page, and a 1787 chart issued by Robert Sayer. 
The tradition took off in the early 19th century, when British publishers like John Hamilton Moore, Robert Blachford, James Imray, William Heather, John William Norie, Charles Wilson, David Steel, R. H. Laurie, and John Hobbs, among others, rose to dominate the chart trade. 
Bluebacks became so popular that the convention was embraced by chartmakers outside of England, including Americans Edmund March Blunt and George Eldridge, as well as Scandinavian, French, German, Russian, and Spanish chartmakers.
Blueback charts remained popular until the late 19th century, when government subsidized organizations like the British Admiralty Hydrographic Office and the United States Coast Survey, began issuing their own superior charts on high quality paper that did not require reinforcement.

Why mastering paper chart navigation remains crucial in the digital age



From Dockwalk by Ted Morley

Capt.
Ted Morley was raised aboard a schooner and has made a career working on board vessels ranging from superyachts to super tankers.
During his tenure at sea, he worked his way up from seaman to master.
He currently holds a USCG Master’s License, Unlimited Tonnage as well as several foreign certificates.
Capt.
Morley actively participates in maritime advisory committees in the U.S.
as well as overseas and is involved in regulatory policy review in the U.S.. 
Captain Ted Morley is the Chief Operations Officer at MPT in Fort Lauderdale, Florida.
He holds several licenses, including a USCG Master Unlimited Tonnage, and is an Associate Fellow of the Nautical Institute as well as a Member of the Royal Institute of Navigation in London.

As paper charts begin to fade away, the navigational skills of understanding them remain critical, says Ted Morley.

The USCG and the MCA, along with virtually every flag state, require practical demonstration of a bridge watch officer’s ability to plot a course, a position and a route on a paper chart, yet the future of paper plotting on board and in training has been in question.
Well, the USCG has just updated their chart exam modules and created several new chart exams on… paper charts.
The critical skill set for a mariner to be able to plot a position, obtain critical information off the chart and create a course line are still considered just that — critical skills.
Electronics are great, but the person looking at them still needs to understand the relationship between the information being displayed and the world around them.

At the end of 2024, the US National Oceanic and Atmospheric Administration (NOAA) will no longer update traditional paper chart products; that timing was determined back in 2016.
Electronic navigation charts (ENCs) will become the only official chart product available from NOAA.
ENCs, known as vector charts, have long been the standard in commercial shipping, and their use is commonplace on vessels that are using an ECDIS display compliant with the International Hydrographic Organization.
In many ways, vector charts are better than paper charts, as they allow for layering of information and user-created data layers, and NOAA is working on standardizing future ENCs to ensure seamless use and updating.
Those of us who have worked as a second mate or a navigator know how much time is spent updating paper charts!
The ability of a system to automatically update a vector chart is a real advancement to safety and efficiency.
Also, the system’s ability to integrate and overlay data from weather sensors, tides and currents, waypoints, etc. can help make voyages more efficient and use less fuel.
At the end of 2024, the US National Oceanic and Atmospheric Administration (NOAA) will no longer update traditional paper chart products; that timing was determined back in 2016

Since 2016, the USCG has allowed the use of ENCs in place of paper charts on board vessels, provided the ENCs are compliant with the regulatory requirements of carriage of charts under Title 33 and 46 CFR, along with compliance with SOLAS certificates.
The RTCM advises the USCG on its Electronic Chart System (ECS) technical requirements for domestic carriage while SOLAS is used as the international standard for carriage.
While devices such as SOLAS-compliant ECDIS units are considered “equivalent to paper charts,” many smaller vessels’ ECS or MFD units and larger vessels’ back-up systems may not.
Making sure that your vessel has the required electronics on board to allow paperless operation is a must, and a qualified consultant must be brought in to ensure you comply with flag state, port state and insurance.

As with the US decision, the UK Hydrographic Office will cease production of Admiralty paper charts by late 2026.
The MCA has issued notices for how vessels can comply; even smaller vessels can reference guidance such as MGN 293, which sets the rules for vessels in commercial service under 150GT and/or under 24 meters (78ft) in length.

Even though the paper chart carriage requirement allows vessels to comply using ENCs, that does not change the requirement of the watch officer to be able to interpret the data on the screen.
An ECS can plot a course, an autopilot can maintain the course and an ARPA can provide collision avoidance — but the role of a mariner is to know how to do the job when those things break.

Monday, July 1, 2024

Portugal (IHPT), a new layer in the GeoGarage platform

 100 nautical charts based on rasterized ENC
 
PT528507 Figueira da Voz harbour 
 
Notes :

- the layer includes Portugal coast, Madeira, Açores, Cabo Verde, plus additional charts for Guiné-Bissau, Sao Tomé e Principe and Angola

- this layer with 100 ENC replaces the few fac-similé raster charts from UKHO (59 charts) based on raster IHPT chart material. The next Q3 update of the British & misc. layer (UKHO) will therefore no longer contain maps for Portugal.

Weather4D & SailGrib renews its GRIB model offering



From NavigationMac & Android-Marine by Francis Fustier

Latest Releases Weather 4D Routing, Routing & Navigation iOS & SailGrib Android mobile apps (compatible with the GeoGarage nautical chart platform) arrive with a completely revised list of weather and ocean models in order to allow users to benefit from the evolution of the offer of international forecasting models. 
 
At the same time, all GRIB files switch to the GRIB-2 format, 
This allows for a reduction in their size and a better compression ratio.

W4D Routing & Navigation is the first version available, Routing and Lite will follow quickly. 
The SailGrib version beta is already online.

The number of models has been increased from 42 up to 54 (from 44 up to 65 taking into account the new resolutions available for some models).
Some evolve, others are added, and some are withdrawn due to less relevance or redundancy. 

Evolving Global Weather models


 
 
• GFS adds a 1 -hour step to the four time steps yet available (3, 6, 9, 12 hours steps).

 
 
• ECMWF IFS now offers three 0.25° resolutions, 0,4° and 1°, four time steps (3, 6, 9, 12 hours steps) and four data : mean wind, pressure, precipitation and air temperature.

 
 
• ECMWF AIFS, European experimental model based on Machine Learning (AI), arrives in all three applications with two resolutions 0.25° and 1°, and three time steps (6, 9, 12 hours steps). Same data as IFS.

 
 
• ICON GLOBAL now proposes four resolutions : 0,125°, 0,25°, 0,5° and 1°, with the same five time steps as the GFS.

 
 
• GDPS (ex GEM) : the Canadian model increases its resolution from 0.24° up to 0.15° and its timespan 6 up to 10 days with four time steps (3, 6, 9, 12 hours steps).

 
 
• ARPEGE Monde increase from 0.5° to 0.25° with four time steps (3, 6, 9, 12 hours steps). 

 

Evolving Regional Weather models


 
 
• ARPEGE Europe now offers five time steps (1, 3, 6, 9, 12 hours steps).

 
 
• ICON Europe now offers five time steps (1, 3, 6, 9, 12 hours steps). 

 

New Regional Weather models


 
 
• HRRR CONUS covers the U.S. as the NAM, but with a very high resolution of 0.025° (1,5NM). Updated every hour, with 1 -hour steps range up to 18 hours steps.

 
 
• ICON D2 covers part of Western Europe with a very high resolution of 0.02° (1,2NM) updated every three hours with range up to 48 hours steps. It is the most accurate of the DWD models.

 
 
• UKV : UK MetOffice model (UKHO) at a very high resolution of 0.05° covering the southern coasts of the British Isles with range up to 5 days with 1, 3, 6, 9, 12 hours steps, updated twice a day, with wind at 10 meters and gusts.

Evolving Ocean models 

 
Waves

 
 
• GFS WAVE : the former WW3 model by FNMOC is now assimilated to the GFS weather model (¹), with same characteristics (resolutions, timespan, steps, updates).

 
 
• MFWAM Global adds several time steps like the ARPEGE Monde model 

Currents


 
 
• COPERNICUS : the name "MyOcean" of current models disappears. Coverages and features remain the same : Global, IBI, ENWS, Baltic, MED. 


New Ocean models 



• HYCOM (Worldwide) : High-resolution ocean currents 0.08°, and low resolutions 0.25° and 0.5°, with 3 -hour steps range up to 7 days.


 
• COPERNICUS SMOC : New Global Model of Combined Tidal and Ocean Currents, with a high resolution of 0.083°(5NM), 0,25°(15 NM) and 0.5°(30 NM) in 1-hour steps. range up to 120 hours steps.

 
 
• WCPS Saint Lawrence River, Canadian MSC model, covers the St. Lawrence with a 0.5NM grid, with 1 -hour steps range up to 84 hours steps. Data provided : mean wind at 10 meters and currents.

 
• IFREMER : very high resolution currents, with grids up to 250 metres on the west and north coasts of France. By 1 -hour steps range up to 100 hours steps.
 
• IFREMER WW3 : combination of wave and current data for the west and north coasts of France, at very high resolutions. By 1 -hour steps range up to 100 hours steps. 

Removed models

Withdrawn models: COAMPS, GEM and WRF. 
 

The back office

A new server infrastructure is implemented, in partnership with SailGrib, to support this change. 
They are calibrated for a significant increase in downloads, increase in resolutions, and the integration of very high resolution current files. 
These high-availability servers are spread over three locations, an automatic failover process to ensure continuity of service. 
Improved procedures for uploading and checking input files should ensure the quality of GRIB output to users..

 

The User Manuals French and English have been updated with these developments, and are yet available to download.
