Subsea Umbilicals The umbilical system provides a means of robust connection between the topside control facilities and the subsea control elements. The umbilical comprises control lines which are used in the operation, maintenance and control of subsea installations and equipment. Umbilical enables control of subsea operations such as the closure of a well from the surface. #subsea #subseaengineering #offshore

HARBOUR ACCEPTANCE TESTS (HAT) A Harbour Acceptance Test (HAT) is a key phase in the commissioning process of a ship, offshore structure, or maritime system. It is conducted before sea trials to ensure that systems and equipment function properly while the vessel or platform is still docked in the harbor. Objectives of a Harbour Acceptance Test Verify System Readiness – Ensures that all onboard systems, including propulsion, navigation, and safety equipment, are operational. Functionality Testing – Tests individual components and integrated systems under controlled conditions. Safety and Compliance Checks – Confirms adherence to regulatory standards and classification society requirements. Fault Detection – Identifies and rectifies any defects before proceeding to sea trials. Crew Training – Allows the crew to familiarize themselves with operations and emergency procedures. Typical Tests Conducted During HAT Power and Electrical Systems (generators, switchboards, UPS, alarms) Navigation and Communication Equipment (radar, GPS, radio) Propulsion and Steering Systems (main engines, thrusters, rudders) HVAC and Auxiliary Systems (pumps, compressors, ventilation) Safety Systems (fire suppression, emergency shutdowns, lifeboats) Once the Harbour Acceptance Test is successfully completed, the vessel proceeds to Sea Acceptance Tests (SAT) for final validation under operational conditions at best.

Subsea Structures EFAT - 1 Extended Factory Acceptance Test (EFAT) is to confirm that subsea equipment or structure is fit for purpose and meets all applicable design requirements. Extended Factory Acceptance Test (EFAT) may be only applicable for several equipment or subsea structures, e.g., subsea trees with sub-assemblies. The System Integrity Test (SIT) is performed to verify the whole system no matter from one supplier only or different suppliers, which shall interface with each other acceptably. Typical FAT items of subsea equipment are: •Flushing, functioning and pressure testing of hydraulic control circuits; •Assembly hydrostatic pressure testing; •Function testing of ROV interfaces - as per attached figure which shows that TDU (Tool Deployment Unit is properly interfaced with SDU (Subsea Distribution Unit)'s valves •Gas testing; •Testing for installation and function SCM; •Thermal insulation test; •Continuity check for cathodic protection (CP). The acceptance criteria for subsea valve function tests in being done by measurements of actuating force, pressure, torque, turns, and/or stroke shall be made for all valves. More identifications and examples for FAT, SRT & SIT will be posted here https://lnkd.in/d9YvuKUk #subsea #saipem #subsea7 #offshore #oilandgas

Allied eParts is proud to present the Hammar Electronic Remote Release System (ERRS). Hammar Remote Release Systems are designed to release liferafts, evacuation systems and other lifesaving equipment on board vessels of all types. With a remote release system, Iifesaving equipment can be released from the bridge or other strategic locations on board and can be deployed irrespective of factors such as weather, smoke or fire, without the crew having to take any unnecessary risks. The function of electric and hydrostatic activation are incorporated within a single release unit, which makes the installation simple and straightforward. The electronic system operates on a 24V source, with an option for an additional back-up battery. This system is highly recommended for the environment with possible risk of explosion, fire or hazardous contamination. Some of the examples are LPG/LNG carriers, chemical tankers, FPSO, oil rigs, etc. The diagram below shows the basic system setup. ATEX/IECEx release units are available for hazardous environment.

Safety Under Pressure: The Role of PSVs and PRVs In city gas distribution networks, managing pressure effectively is critical to ensuring uninterrupted operations and safety. Devices like Pressure Safety Valves (PSVs) and Pressure Relief Valves (PRVs) are indispensable in maintaining pressure within safe limits. But did you know these two valves work differently? A PSV is designed for quick action—opening instantly when pressure exceeds the safe threshold. It prevents potential safety incidents by swiftly releasing excess gas. In contrast, a PRV operates more gradually, releasing pressure in controlled amounts to maintain system stability. While often used interchangeably, PSVs are ideal for emergency situations, while PRVs suit systems that demand steady and measured pressure control. Both are vital in ensuring the safe and efficient operation of gas pipelines, equipment in the PNG network, CNG equipments, and city gas networks. Pressure relief devices aren’t just mechanical components—they are silent guardians of safety. #CityGasDistribution #PNG #CNG #PipelineManagement #PressureControl #GasSafety #Engineering

SEA ACCEPTANCE TEST (SAT) A Sea Acceptance Test (SAT) is a critical evaluation process conducted on ships, offshore platforms, or other maritime systems to verify their performance and compliance with contractual, regulatory, and operational requirements. SATs are usually performed after successful Harbor Acceptance Tests (HAT) and before the final delivery of the vessel or system. Objectives of SAT • Verify that the vessel or system functions correctly in real sea conditions. • Confirm that installed equipment and systems meet performance specifications. • Identify and resolve any defects before final acceptance. • Ensure compliance with safety, classification, and regulatory standards. Key Components of a SAT • Propulsion & Maneuverability Tests • Engine performance (main and auxiliary engines). • Steering and thruster operations. • Speed and endurance trials. • Navigation & Communication Systems • Radar, GPS, AIS, and ECDIS verification. • Radio and emergency communication tests. • Safety & Emergency Systems • Fire detection and suppression system checks. • Life-saving equipment inspection. • Emergency power and lighting tests. • Power Generation & Electrical Systems • Load tests on generators and electrical distribution. • UPS and battery backup systems verification. • HVAC & Environmental Control • Ventilation, heating, and cooling performance. • Noise and vibration level measurements. • Cargo & Handling Systems (if applicable) • Cranes, winches, and cargo handling tests. • Ballast system performance. • Stability & Structural Integrity • Ballast and trim adjustment tests. • Structural stress monitoring. SAT Process • Planning & Preparation • Defining test criteria and performance benchmarks. • Ensuring safety measures and risk assessments are in place. • Execution at Sea • Conducting tests under real operational conditions. • Recording data and observations. • Analysis & Reporting • Evaluating test results against specifications. • Documenting any non-conformities and corrective actions. • Final Acceptance • If all tests are passed, the vessel or system is officially accepted. • Any outstanding issues are addressed before commissioning.

Take the time to do a mid-day restart. Update the crew on the job, progress, goals, hazards, and ways to mitigate hazards together. It’s a good way to get your head back in the game and stay focused. . Quality and Safety.
