Heave-Compensated Landing System The heave-compensated landing system (HCLS) used by Delmar consists of the following equipment: a compensating buoy system, compensating belly chain, and pendant wire. Figure below shows an example of the HCLS installation of subsea structure with an anchor handling vessel (AHV) The buoyancy system suspends the subsea structure, keeping the system close to a neutrally buoyant condition in the vertical direction. The subsea contracture is lowered to the seafloor in a controlled manner by paying out wire from the AHV, which transfers more chain and thus more weight to the buoyancy system. As more chain is added, the added weight overrides the buoyant forces, causing the subsea structure to slowly sink. The length and configuration of the chain are the compensating portion of the system. HCLS has a very good heave compensation effect, but it is difficult and complicated to get the subsea equipment overboard from the barge. #subsea #offshore #saipem #subsea7

Our track record says it all! 👏 Flashback to 2005, when hurricanes in the US highlighted the need to protect critical areas of lower hull pontoons from large environmental loads encountered during severe storms. Global SantaFe identified a particular risk to the thruster rooms located inside their Development Driller 1's pontoons. The pontoons needed to be reinforced, and after detailed analysis, SPS was specified as the appropriate solution to enhance the resilience of the rig with: ✔️ Puncture resistance for 2t drill collars dropped 37m ✔️ No disruption to critical path activities in the thruster room below ✔️ Deceleration -300g: impact energy 1100 kj This project was completed in 3 just weeks! So, for efficient and effective robust repairs for offshore vessels, the choice is CLEAR.

[PROJECT] 2H helped a client determine the cause of a platform well conductor failure and assess the likelihood of a similar failure occurring on another well slot. Discover how 2H’s in-depth knowledge of platform well conductors and expertise in subsea fatigue assessments enabled our client to make a probabilistic-based assessment of the risk involved in bringing wells back online once remedial measures had been taken to re-centralise the conductors. 📍 North Sea https://lnkd.in/eYQW3xdR

A chain is only as strong as its weakest link. Several type of offshore structures such as FSO/FPSO and SBM/CALM buoys utilize anchor chains to hold in position. It is common to see multiple anchor chains for each structures. Not small chain like bicycle chain. A single link chain for these structures can be almost 1m long and weight at few hundreds kilogram. A broken anchor chain is no good. It doesn't serve its purpose. Later the FSO or SBM buoy would float away if all anchor chains fails. Hence it is important to check the condition of the chain links at the high stress area & corrosion is mostly expected. The subsea inspection performed on the anchor chain are: ⚠ Visual Inspection ⚠ Marine Growth cleaning of chain links at selected location ⚠ Selected Chain Links Wear measurement to record its current dimension to compare with as-built data ⚠ Measurement of corrosion pitting if observed ⚠ CP measurement ⚠ Chain angle measurement These data would be utilize for analysis and understand where is the weakest link, so the necessary remediation work can be performed if necessary. As the weakest link would be the anchor chain's Achilles heel. #worklife #pakciksubsea #offshore #oilandgas #oilandgasindustry #subseainspection #subseairm

Subsea Manifold Installation The installation of a subsea structure/manifold requires careful planning and coordination with workboats, a crane barge or floating drilling vessel, and acoustic and/or electrical location equipment. The choice of installation vessel is based on vessel availability, existing mooring equipment, adequate crane capacity, and suitable deck space for transportation. Video below illustrates a manifold installation from a MPCV. The manifold is landed and locked to the suction pile. A ROV is used to monitor the direction and position of the manifold during the entire installation procedure. #subsea #offshore #oilandgas

A bitt, often referred to simply as a "cleat" serves as a pivotal component in anchoring a ship securely. It is essentially a loop or ring-shaped fixture firmly attached to the deck of the vessel. When dropping anchor, the chain or rope attached to the anchor is passed through the bitt, providing a stable point of attachment. This mechanism allows the ship to be anchored firmly in place, resisting the forces of wind and currents. By securing the anchor to the bitt, the ship remains stationary, maintaining its desired position and ensuring the safety and stability of the vessel. #vdengetechnology #didyouknow #shipbuilding #shiprepair #drycargovessel #oilchemicaltanker #supplyvessel #sea #ocean #marine #maritime #seatransport #bitt #vessel #ship

CASE STUDY: bp approached TSC Subsea with a unique challenge: to conduct an internal inspection of an unused unpiggable riser located on one of their North Sea offshore platforms. This particular 365 mm (14 in) diameter duplex riser had been installed initially as a spare and had never been put into operation. Due to an upcoming development project, bp aimed to commission the riser for service. However, before proceeding, they needed definitive assurance regarding its fit-for-service. Discover how TSC Subsea overcame the challenge with their TRITON tethered in-line Inspection (ILI) pipe crawler equipped with ACFM and Phased Array technology. 👉 https://lnkd.in/evKY2Uhf #TSCSubsea #TRITON #PipelineIntegrity #Innovation #SubseaEngineering #offshore #offshoreoilandgas
