Our POSH Gusto and POSH Gaia harbour tugs have set sail for Myanmar!
Given the travel restrictions amid COVID-19, it was no easy feat to get the crew for this charter, which will see the two 4,000 BHP vessels provide berthing & unberthing, towing and standby firefighting support for CNTIC and V-Power group in Myanmar waters.
We couldn’t have done this without the strong support from Maritime and Port Authority of Singapore and our crew, as we managed to observe all required safety measures for crew changes in an efficient manner.
A safe voyage and a successful completion to all!

Dive system providers are developing bespoke solutions for subsea vessel owners
Looking to offer integrated diving solutions on its vessels, Singapore-based POSH Subsea inked a deal in January with Unique Group to design, manufacture and deliver classed air and saturation dive systems.
Over the next two years, Unique Group will supply classed air and saturation diving equipment, compliant to the stringent Oil and Gas Producers (OGP) 468 and International Marine Contractors Association (IMCA) guidelines, as well as consumables and technical support during and post installation.
POSH Subsea, a unit of PACC Offshore Services Holdings Ltd, operates specialised vessels capable of supporting subsea inspection, repair and maintenance (IRM), construction and installation.
To minimise operational downtime, Unique Group is supporting the contract with its Unique Equipment Manager (UEM), a digitalised planned maintenance system that integrates with the dive systems to enable POSH to track the condition of the equipment more accurately.
Subsequent to its contract with POSH Subsea, Unique Group secured an order from Kazakhstan-based subsea services provider FSDS Group for a bespoke air dive systems. In June, Unique Group’s Diving & Life Support division in Sharjah delivered such a system in eight weeks.
ABS classed and built to IMCA guidelines, the diving system comprises a dive control station, diver decompression chamber, diver monitoring and life support, air storage, high- and low-pressure compressors and main diver and standby diver hot water machines.
FSDS Group chief executive Matt Richards, said: “Our technical team worked rigorously with the engineering team at Unique Group to ensure that the system was designed to our specific requirements.”
UK-based JFD, part of James Fisher and Sons plc, was similarly challenged in September with an order to deliver saturation diving products rated to a depth of 500 m. JFD designed and delivered the new products as part of a saturation diving system for a leading offshore service provider.
For the contract JFD developed new environmental control systems, gas reclaim and life support products that provide saturation dive capability. To meet the requirement for 500 m-rated products, JFD updated its existing technology to provide greater performance capacity, as well as developing entirely new products, all of which had to be verified and proven at this lower operational depth. The new technology utilised by JFD has enabled products to be designed that are able to cope with increased pressure, increased ability to heat and which cool the divers’ living environment; they also offer increased transfer of gas and fluids at extreme operational depths.
JFD has previously modified its range of equipment to meet customer requirements. In 2014, as part of a saturation diving system built for the Russian Navy to support submarine rescue operations, JFD’s saturation diving products were enhanced for 450msw operation and incorporated within the diving vessel Igor Belousov.
In October 2018, our anchor handling tug supply vessel ("AHTS") POSH Defender supported the complex transportation of topside and boat-landing from the Ocean Might Yard in Kuching, Malaysia, to the D28 oil field approximately 172 nautical miles off Kuching, marking one of the biggest loadouts of its kind in our industry.
The project tested the mettle of our crew and we executed the project successfully, supporting our clients' business needs.
One unique aspect of the loadout was the sheer weight involved. The total weight of the deck cargo loaded onboard was 446 metric tonnes ("MT"), a heavier than usual load.
The topside and grillage were loaded onto the extreme left of the vessel, which was required to hold dynamic positioning ("DP") approximately two metres from the installation during the offloading of the topside. To ensure that POSH Defender was up to the task, we had to carefully manage the stability calculations involved with the loading of such a massive weight, while taking into consideration the sheer size of the topside.
The concerns were that the heavy load at the extreme ends of POSH Defender might lead to high bending stresses mid-ship. Based on the stability calculations, POSH had to ensure all stability criteria and bending moments for loadout and transportation were within the permissible limits. We refined this multiple times with our client for more than a month to ensure full compliance with International Maritime Organisation Class & Marine Warranty Surveying ("MWS") requirements.
Besides weight and size considerations, we also had to abide by five different inspections - Offshore Vessel Inspection Database ("OVID"), Offshore Support Vessel Inspection System ("OSVIS"), MWS, 2H Offshore and PETRONAS - for the release of the Green Letter to close the punch list.
Managing this massive project seamlessly, safely and completing it on schedule without issue was a major achievement by the team. This speaks to our operational excellence, high standards of service and safety as well as steadfast reliability which we always strive to achieve.
