General assistance during Class Surveys
We support the surveyor and the crew ensuring all requested safety systems, machinery, and structure are prepared, operational, and accessible during the ship’s class surveys.
General arrangements
We support our clients with any and all kinds of assistance for GA.
Checking of remote control quick closing valves, stopping devices, valves, ventilators
Quick closing valves (QCVs) on ships must be tested on a regular basis to ensure remote closure of fuel and lube oil tanks from safe, external locations, preventing engine room fire hazards. Proper inspection includes verifying pneumatic and hydraulic operation, checking for seized components, and resetting valves, ensuring compliance with SOLAS to ensure the system is not intentionally blocked or modified.
Checking of main engine and auxiliary engines
Checking vessel’s main engines and generators involves a routine focusing on fluid levels (oil, coolant, etc.), belt tension, seawater strainer cleanliness, and identifying leaks (oil, water, etc.). Key steps include inspecting fuel filters, running engines to confirm smooth operation, checking exhaust for cooling water flow, and verifying that batteries are charged. At Mansueto Marine our team of mechanics and engineers are highly skilled to carry all these kinds of operations and much more.
Crank web deflection of main engine and diesel generator
Crank web deflection measurement is a critical maintenance procedure for yacht main engines and generators to detect misalignment or bearing wear by measuring the deformation of the crankshaft as it rotates. You can rely on our team of experts to ensure safety and efficiency of all your systems.
Checking of main and auxiliary steering gear including their appliances and control system
Checking main and auxiliary steering gear on a yacht involves testing full rudder movement (hard port to starboard) from all bridge positions, verifying hydraulic pressures/oil levels, and confirming alarms within 12 hours of departure. This includes confirming the auxiliary system can immediately engage and operate at reduced speed. Inquire us to obtain your tailored quote for this service.
Checking of the bilge system including remote control mechanism and bilge filling level monitor
Checking the bilge system on a yacht, including remote control mechanisms and filling level monitors, requires a comprehensive approach to verify that electrical, mechanical, and monitoring components operate reliably to prevent flooding. Don’t neglect the importance of having your ship’s systems checked by a professional.
Checking and cleaning of the tank (gas free included)
Cleaning and checking yacht tanks (fuel, water, or sewage) requires strict adherence to safety protocols, particularly ensuring a “gas-free” environment before personnel entry, as these are classified as confined spaces. The process involves specialized cleaning, inspection for structural issues or corrosion, and certification by qualified personnel. Inquire us to get your detailed quote within 24 hours.
Checking of the main and emergency power supply system including the switch gear and other electrical installations
Checking yacht power systems involves testing the automatic startup of the emergency generator within 45 seconds during a simulated blackout and verifying the emergency switchboard powers critical systems (lights, navigation, fire pumps). Inspections must include testing battery banks, checking for loose wiring in AC/DC panels, and confirming the emergency generator is in a separate space.
Insulation resistance of generators and essential electrical motors, including cabling and switchboard
Insulation resistance (IR) testing, commonly known as “Megger” testing, is critical for maintaining the safety and reliability of yacht electrical systems, preventing fires, and ensuring compliance with standards like IEC 60092. It measures the integrity of dielectric insulation in motors, generators, cabling, and switchboards by applying high DC voltage and measuring leakage in megaohms. Inquire us to know more about the wide range of solutions we can propose.
Checking of the bilge system including remote control mechanism and bilge filling level monitor
A comprehensive check of ship’s bilge systrem involves verifying the physical pump, the electrical float switch, the high-water alarm, and any remote app-based monitoring systems. This is not a job for beginners and you need an expert. Here we are.
Structural calculation according to Class rules
Structural calculations for yachts follow specific Class Rules (e.g., Lloyd’s Register, DNV, ABS, RINA) or ISO 12215 standards to determine scantlings (dimensions/thicknesses) for hull, deck, and appendages. You can rely on our team of experts to ensure these operations are carried according to the best industry practice.
