Understanding UMA (UMS) Ships and Their Operational Requirements
UMA (Unattended Machinery Area) ships, sometimes referred to as UMS, are designed for machinery and equipment operation without constant watch-keeping personnel. This article outlines the specific machinery included, stringent safety requirements, and the need for meticulous ship design. It emphasizes fire safety measures, prevention of flooding, alarm systems, and communication means, all crucial for ensuring safe and continuous operation.
The Science of Ship Propellers: From Basics to Future Innovations
This technical article delves into the world of maritime engineering, highlighting the central role of ship propellers in vessel propulsion. It explores the foundational principles of propellers, their various types, materials, and construction, and provides a glimpse into the future of ship propulsion technology.
The wind propulsion technology
A key strategy to lessen the industry's carbon footprint and aid in the fight against climate change is wind propulsion. Numerous technological developments present excellent opportunities. These approaches, including ours, enable the creation of effective and affordable wind propulsion systems that can be applied to a wide range of ships.
Plate Type Heat Exchangers
Heat exchanger is a device that transfers heat through a conducting wall from one fluid to another. Heat exchangers are used to transfer heat from a hotter fluid (liquid or gas) to a colder fluid. In this article, we will briefly introduce the equipment and some common faults in them.
Crankcase Relief Valve
SOLAS regulations to prevent crankcase explosions came into place after a particularly devastative explosion that claimed the lives of 28 people onboard MV Reina Del Pacifico in 1947.
Since then, many detection and preventive measures have been added to ships to eliminate or at least reduce the risk of this phenomenon. In this article, we shall take a look at what crankcase explosion is, how it occurs and what can be done to prevent it.
Spark erosion on main bearings
Spark erosion can occur if electrical potential in the crankshaft discharges through the main and thrust bearings, which if undiscovered can cause critical wear on the main bearings, and consequently severe crank train damage.
Introduction to Pressure Safety Valve
The primary purpose of a pressure safety valve is the protection of life, property and environment during an over-pressure event in a pressurized vessel or equipment. An over-pressure event refers to any condition which would cause pressure in a vessel or system to increase beyond the specified design pressure or maximum allowable working pressure.
Ammonia as a marine fuel
Ammonia has attracted wide interest as a source of zero emission fuel for shipping. Ammonia has the key benefit of being easier to store than hydrogen, i.e. nearly identical to propane (LPG) at low pressure under ambient conditions. Hence, the cost of storage per energy unit is significantly cheaper than either hydrogen, electricity in batteries or LNG.
Oil Record Book
This is necessary in order for authorities to be able to monitor if a vessel’s crew has performed any illegal oil discharge at sea. All officers and crew onboard need to recognize that recording of ORB is required by the rules and the records are critical.
