4.4 Ships carrying liquid cargo in bulk

4.4.1 The service notations related to self-propelled ships intended for the carriage of liquid cargo in bulk are listed in [4.4.2] to [4.4.7].

with service notation combination carrier/OOC ESP


4.4.2 Oil tanker, for sea going self-propelled ships which are constructed generally with integral tanks and intended primarily to carry in bulk crude oil, other oil products, or oil-like substances having any flash point, or liquid at atmospheric pressure and ambient temperature (or thus maintained by heating). This notation may be assigned to tankers of both single and double hull construction, as well as tankers with alternative structural arrangements, e.g. mid-deck designs.
The service notation may be completed by the following additional service feature, as applicable:

The additional requirements of Part D, Chapter 7 are applicable to these ships.
For ships with integral cargo tanks, the service notation oil tanker is always completed by the additional service feature ESP (i.e. oil tanker ESP), which means that these ships are submitted to the Enhanced Survey Program as laid down in Ch 4, Sec 3.

4.4.3 Chemical tanker, for sea going self-propelled ships which are constructed generally with integral tanks and intended primarily to carry chemicals in bulk. This notation may be assigned to tankers of both single or double hull construction, as well as tankers with alternative structural arrangements. Typical midship sections are illustrated in Fig 5, or a midship section deemed equivalent by the Society. The additional requirements of Part D, Chapter 8 are applicable to these ships.
The list of products the ship is allowed to carry is attached to the Certificate of Classification or the Certificate of Fitness, where issued by the Society, including, where necessary, the maximum allowable specific gravity and/or temperature.
For ships with integral cargo tanks, the service notation chemical tanker is always completed by the additional service feature ESP (i.e. chemical tanker ESP), which means that these ships are submitted to the Enhanced Survey Programme as laid down in Ch 4, Sec 4.

4.4.4 Liquefied gas carrier, for ships specially intended to carry liquefied gases or other substances listed in Pt D, Ch 9, Sec 1 of the Rules. The additional requirements of Part D, Chapter 9 are applicable to these ships.
The list of products the ship is allowed to carry is attached to the Certificate of Classification or the Certificate of Fitness, where issued by the Society, including, where necessary, the conditions of transportation (pressure, temperature, filling limits).
The service notation may be completed by the following additional service feature, as applicable:

4.4.5 FLS tanker, for ships specially intended to carry in bulk flammable liquid products other than those covered by the service notations oil tanker, chemical tanker or liquefied gas carrier.
The list of products the ship is allowed to carry may be attached to the Certificate of Classification, including, where necessary, the maximum allowable specific gravity and/or temperature.
The service notation may be completed by the additional service feature flash point > 60°C, where the ship is intended to carry only such type of products, under certain conditions.
For ships intended to carry only one type of cargo, the service notation may be completed by the additional service feature indicating the type of product carried, e.g. FLS tanker-edible oil.
The additional requirements of
Part D, Chapter 7 are applicable to these ships.

4.4.6 Tanker, for ships intended to carry non-flammable liquid cargoes in bulk other than those covered by the service notations in [4.4.2] to [4.4.5], such as water.
The list of cargoes the ship is allowed to carry may be attached to the Certificate of Classification.
For ships intended to carry only one type of cargo, the service notation may be completed by the additional service feature indicating the type of product carried, e.g. tanker-water.
The additional requirements of Part D, Chapter 10 are applicable to these ships.

4.4.7 Refer also to [4.3.4] and [4.3.5] for combination carrier intended to carry alternatively oil products and dry cargo in bulk in cargo holds/tanks.
