Aframax

A category of medium-sized oil tanker with a capacity typically ranging from 80,000 to 120,000 deadweight tons (DWT). Aframax vessels are vital in the crude oil transportation segment because they can access a wide range of ports worldwide, including those with size and draft restrictions.


Anchor Handling Tug Supply

An Anchor Handling Tug Supply (AHTS) vessel is a specialized ship designed for various offshore operations. These vessels handle anchors, tow rigs, and barges to and from offshore locations. They also serve as supply vessels, transporting essential supplies and equipment to offshore platforms. Additionally, AHTS vessels often feature powerful winches and dynamic positioning systems (DPS)...


ANNEX VI (MARPOL)

Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL) is a regulatory framework established by the International Maritime Organization (IMO). It addresses air pollution from ships, setting standards for emissions of sulfur oxides (SOx) and nitrogen oxides (NOx), as well as guidelines for energy efficiency in ship design. Annex VI...


Auto Drain valve

An automatic drain valve is a device used to automatically remove accumulated liquids, such as condensate or other fluids, from a system without manual intervention. It typically operates based on preset conditions such as time intervals, liquid level, or pressure thresholds. In industrial and maritime applications, automatic drain valves are commonly employed in compressed air...

Break-bulk

Break-bulk refers to the method of transporting cargo that is not in containers or bulk but instead loaded and unloaded individually. This type of cargo includes items such as crates, barrels, bags, and pallets. Accordingly, break-bulk ships are a subcategory of general cargo ships. Break-bulk shipping involves handling each piece of cargo separately, often requiring...

Buffer Vessel

A buffer vessel is a container or tank designed to minimize pressure fluctuations within a system by absorbing or dampening variations in pressure. Typically used in industries such as maritime, manufacturing, and oil and gas, a buffer vessel helps maintain stable operating conditions by storing excess fluid or gas temporarily.
