This document specifies the methodology to conduct computational modelling of ultraviolet (UV) reactor designs for ballast water management systems (BWMS) that incorporate ultraviolet disinfection technology (UVBWMS). The computational modelling is used to calculate the UV reduction equivalent dose (RED) and to compare calculated REDs of the scaled reactor to its base reactor. REDs are determined using organisms with a given dose response. NOTEÂ Â Â Â Â Â Â Â Â Â Â The IMO requires validation of the computational model. The simulation of a physical UV reactor using a computational model requires that the model be validated (i.e. it performs as intended and reflects the correct physical constraints) and verified (i.e. produces outputs consistent with empirical data). A model developed according to this document is intended to validate the performance of simulated but untested, scaled UV reactors, where the simulation has been verified with test data from base model UV reactors within the product line. As a complete UV BWMS typically incorporates other treatment methodologies such as filters, the impact of changes to external subsystem performance on the overall BWMS is not considered in this document.

This document defines terms, specifies test methods and provides reporting requirements for marine sensor specifications to ensure a consistent reporting by manufacturers. It is applicable to those devices known as conductivity-temperature-depth (CTDs), sound velocity probes, multi-parameter sondes and dissolved gas sensors, that measure parameters such as conductivity, temperature, pressure, sound speed, dissolved oxygen, turbidity, pH, and chlorophyll in seawater. It is also generally applicable to all marine environment instruments. NOTE 1: A CTD directly measures conductivity, temperature, and pressure. Depth is derived from pressure using an equation. NOTE 2: The term sound velocity probe is widely used to describe instruments that measure sound speed. In this document the term ?sound velocity is used when describing the type of sensor, and the term sound speed is used when describing the parameter or measurand, but these terms can be used interchangeably.

This document specifies a methodology for establishing quantitative performance data for oil skimmers for recovery of oil with high viscosity (above 50 000 cP), so the end user can objectively judge, compare and evaluate the design and performance of different skimmers. The methodology applies to testing in a basin and requires control of oil properties and oil slick characteristics. The method is applicable to all types of skimmers provided that the equipment dimensions are within the physical limitations of the test basin. The test procedure provides full-scale test results for the unit tested, under controlled conditions, and for one or more classes of highly viscous oil. Attention is drawn to the care required when applying the test results to predict a realistic skimmer performance under field conditions. For dedicated/in-built systems, the test procedures outlined in this document are only applicable to the skimming device as such, not to the entire skimming system.

Bonding of glazed openings where the glazing material is subjected to loads from global ship motions (bending, shear force and torsion), which are considered as structural glazed openings, are outside the scope of this document. Quantitative identification of the global deflection is also outside the scope. Additionally, this document is limited to bonding that exhibits elastic behaviour, and excludes rigid bonding and nonlinear elastic bonding. The design of the bonding for the following installation types is outside the scope of this document: — fire protected areas; — glazed bulwarks; — underwater glazing; — pool glazing; — glazing for use in polar areas; — unstepped IGUs.

This document establishes a uniform, safe and consistent approach to the technical training of personnel for the maintenance, thorough examination, operational testing, overhaul and repair of lifeboats (including free-fall lifeboats) and rescue boats (including fast rescue boats), launching appliances and release gear. It also provides the necessary information for interested parties to grant authorization, effectively evaluate and audit training, supporting the IMO Requirements, Section 3. It specifies the training requirements for the Level 1 controlled environment education and technical training for personnel certified by a manufacturer or an authorized service provider to carry out maintenance, thorough examination, operational testing, overhaul and repair of lifeboats (including free-fall lifeboats) and rescue boats (including fast rescue boats), launching appliances and release gear. The Level 1 training is split into two Stages, both covered in this document: — Stage 1, Service Technician technical controlled environment education and training, has five modules that consist of classroom-based theory followed by practical sessions. The five modules encompass the scope and range of technical knowledge and skills required to assume type specific design coverage of survival craft, release systems, davits and winches. The modules focus on supporting the requirements in part of the IMO Requirements, paragraphs 8.1, 8.2.1.1-8.2.1.6, 8.2.2, and 8.2.3. — Stage 2, Service Technician technical controlled environment experience and assessment, where candidates undertake a minimum of four supervised scenarios-based practical exercises assessments covering the range of type specific complete systems for which they will be certified. This document is intended to be used in conjunction with ISO/PAS 23678-1, ISO/PAS 23678-2 and ISO/PAS 23678-4. This document is applicable to the following types of lifeboats (including free-fall lifeboats), rescue boats (including fast rescue boats), launching appliances and release gear.

Winch types: a) twin drum; b) single drum; c) gravity-lowering, electric hoisting; d) gravity-lowering hydraulic hoisting; e) hydraulic hoisting and lowering. Hook release system types: a) on-load/off load (load not over centre); b) on-load/offload (load over centre); c) off load; d) freefall hydraulic; e) automatic.
