GLOSSARY
Angle of Loll - An angle of Loll is where a vessel initially has unstable equilibrium, where G(Centre of Gravity) is above M (Metacentric Height). The resulting angle of heel causes G to dropbelow M again, this angle that the vessel is heeled to and settled at is known as the Angle of Loll.
Ballast Tank - Any tank which is used to contain Seawater in order to assist with raising orlowering the draft of the vessel and maintaining stability.
Bending Moment - The Bending Moment at a point is the algebraic sum of the moments of theforces to one side of the point considered. A bending moment above the neutral axis will bepositive and below the neutral axis will be negative.
Bilge - The space at the bottom of the vessel which collects spills and leaks for a compartmente.g. Pumproom or Engine room Bilges
Bunker System - The pipework and tanks on a ship / vessel used to transport fuel onto andaround the vessel.
Confined/Controlled Space Entry - Any space that requires a control measure to be put inplace to allow safe entry. This is normally a Confined Space Entry Permit (e.g. restricted space
machinery space; enclosed space ballast tank).
Deck Operator - A person who is utilised to monitor, operate or control equipment externally onthe Process or Marine Decks of a vessel/FPSO/FSU.
Free Surface Effect - Free Surface Effect is defined as a virtual loss of GM. When an externalforce heels a vessel, the liquid in the vessel is free to move also. The liquid will move to the lowside of the vessel causing G to move off the centreline. The result is that the GZ (rightingmoment) of the vessel is reduced from what it would be if the liquid were not free to move and theeffect is that the vessel will have a smaller GM than is actually the case.
Field Operations - Any operation that occurs within the extremities of the Installation 500m Zone;
includes surface, subsea and airborne operations.
Heavy Weather - Conditions which are outwith Installation accepted Norms for continued safeoperations, includes Wind, Sea Swell conditions.
Heel - A ship / vessel is said to be heeled when she is inclined by an external force, e.g. wheninclined by the action of wind or waves.
Hogging - A vessel is HOGGED if too much weight is loaded at either end causing the amidshipsdraught to be less than the fwd and aft draughts
List - A ship / vessel is said to be listed when she is inclined by forces within the ship / vessel,
e.g. when a weight is moved transversely within the ship.
Marine Systems - Any system which requires a Marine Operator to have input into controlling theinput or output of the system.
Offload Station - The area of the Installation or vessel where cargo is exported/offloaded toanother facility e.g. Offtake Tanker.

Sagging - A vessel is SAGGED if too much weight is loaded in the middle causing the amidshipsdraught to exceed the fwd and aft draughts
Shear Force - The Shear Force at a point is the algebraic sum of the forces acting to one side ofthe point considered. A shear force above the neutral axis is considered positive and below theneutral axis is considered negative.
Stability - The subject of maintaining a vessel afloat in a safe condition
Stiff Ship - A stiff ship is where she has a large righting moment at small angles of heel. Anexample is when a vessel has a large GM caused by too much cargo loaded low down in thevessel (double bottom ballast tanks).
Synoptic Chart - A chart of an area of operation that has an overlay of the weather patterns thathave developed or are developing in the area. Used to predict / forecast the expected weather ina specific location.
Tender Ship - A tender ship is where she has a small righting moment at small angles of heel.An example of this is when a vessel has a small GM caused by loading cargo high up in the
vessel (timber deck cargo or too much process deck added to a conventional tanker)
Tensile Loading - Any external load applied to a material in such a way as to cause an extensionof the material, results in Tensile Loading.
Validate - To confirm or corroborate
Verify - To check or determine correctness
