(a) International Safety Management (ISM) Code means the International Management Code for the Safe Operation of Ships and for Pollution Prevention as adopted by the Assembly, as may be amended by the Organization.
(b) Objective evidence means quantitative and qualitative information, records or statements of fact pertaining to safety or to the existence and implementation of a safety management system element, which is based on observation, measurement or test and which can be verified.

(a) The efficiency of diesel engines, especially of two-stroke low speed diesels, is almost independent of load over a wide load range. Furthermore, low load running without any limitation is possible down to approximately 20% of maximum continuous rating (MCR), while still ensuring high efficiency and reliability, irrespective of the plant running program.

(b) Essentially, diesel engine combustion comprises a series of batch processes, whereas the gas turbine uses continuous combustion. In the batch process, higher initial temperatures and pressures can be used than in the gas turbine, since the exposed components are cooled at the end of each process and between processes. The thermal efficiency can therefore be higher in the diesel than in the gas turbine.
(c) Each piston stroke constitutes a batch process, and the slower it can be while still maintaining its adiabatic thermodynamic condition, the more efficient it can be. An added advantage of the slow process that takes place in a low speed engine is that the ignition delay which may occur, depending on fuel quality and engine geometry, has less impact on a low speed engine.
(d) While a low speed engine often gives a longer ignition delay than its medium speed counterpart with the same fuel, the ignition delay is still proportionally shorter in a low speed engine, in terms of degrees of crankshaft angle. This is one of the reasons why a low speed engine is considered more forgiving than other types of machinery when low-quality, low-cost fuels are used.
