Definition

Noun: - A compartment in a ship's hull: A "bilge well" is a specifically constructed low point or sump within the bilge area of a ship's hull. Its primary function is to collect water, seepage, and other liquids that accumulate at the bottom of the vessel so they can be efficiently removed.

Usage

The term is used exclusively in a nautical or marine engineering context to describe a structural feature of a watercraft designed for drainage and maintenance. - The crew checked the bilge well daily to monitor the amount of seepage water. - Before the voyage, ensure the pump intake is clear and positioned correctly in the bilge well.

Advanced Usage

• "to sound the bilge well": A standard nautical procedure involving using a measuring stick (a sounding rod) to determine the depth of liquid collected in the bilge well, which indicates the rate of leakage or accumulation.
  • The first mate's duty was to sound the bilge well every watch and log the findings.

Variants and Related Words

• Bilge (noun): The broadest part of a ship's hull, specifically the curved part where the bottom meets the side; more generally, the lowest internal part of the hull where water collects.
• Bilge pump (noun): The pump used to remove water from the bilge or bilge well.
• Sump (noun): A general term for a low pit or well that collects liquid, making it a functional synonym in non-nautical contexts (e.g., in a basement or machinery space).

Synonyms

• Sump (in a general engineering sense)
• Drainage well (descriptive synonym)

Notes on Meaning

The "bilge well" is a sub-component of the bilge system. While "bilge" refers to the entire low area of the hull, the "bilge well" is the specific, often slightly recessed, compartment designed to centralize fluid for pumping. It is a critical feature for maintaining a vessel's stability and safety.

Noun

1. (nautical) a well where seepage drains to be pumped away
