Inclination Test - From RainRyder on Investor Village Inclination Test ?
I believe the FPF 1 is now undergoing the "Inclination Test" ... (but WTFDIK)
From my last post the FPF 1 was moved free from mooring restraints still inshore and in calm water (see below)
From 2016-07-11 06:52 ET - News Release ...
Les Thomas, chief executive officer, commented:
"The FPF-1 works are now being finalized, with preparation and performance of the inclination test being the only work required prior to the vessel exiting the yard.
The following Thanx to Chart Trader 2000 on the UK ADVN Board .....
From Wikipedia, the free encyclopedia.........
An inclining test is a test performed on a ship to determine its stability, lightship weight and the coordinates of its center of gravity.
The test is applied to newly constructed ships greater than 24m in length, and to ships altered in ways that could affect stability. Inclining test procedures are specified by the International Maritime Organization and other international associations. The weight of a vessel can be readily determined by reading draughts and comparing with the known hydrostatic properties. The metacentric height (GM), which dominates stability, can be estimated from the design, but an accurate value must be determined by an inclining test.
The inclining test is usually done inshore in calm weather, in still water, and free of mooring restraints to achieve accuracy.
The GM position is determined by moving weights transversely to produce a known overturning moment in the range of 1-4 degrees if possible Knowing the restoring properties (buoyancy) of the vessel from its dimensions and floating position and measuring the equilibrium angle of the weighted vessel, the GM can be calculated.
Inclinings can be performed in service by averaging out the effects of motions caused by waves. As in a new ship test, the weight shifts have to be known and the angles of tilt measured. The effects of any mooring can be calculated and deducted. A series of weight (usually ballast) movements are used to obtain an average and variance for GM.
