T0838 Att 4 -Trawl Diagram~1.pdf

This is a technical specification diagram attachment for a charter services contract issued by the New Jersey Department of Environmental Protection (NJDEP) for ocean vessel trawl survey operations. The document, labeled as Attachment 4, provides detailed specifications for a Three-in-One Trawl design that serves as the equipment standard for the trawl survey services. The diagram illustrates both the top and bottom configurations of the trawl net, including mesh specifications, dimensions, and construction details such as 3½ inch mesh measurements, selvage bars, knit depth specifications, and loop configurations. The trawl design incorporates specific materials including 3-inch double 4mm poly construction with dimensions of 380 x 12 cm, along with detailed measurements and component specifications necessary for proper net assembly and deployment.

The technical specifications outlined in this diagram establish the mandatory equipment requirements that bidders must meet when providing trawl survey services under the NJDEP contract. The standardized trawl design ensures consistency and comparability in survey data collection across all contracted vessel operators. This attachment serves as a binding specification document that contractors must comply with when performing ocean vessel trawl survey work, making it essential for bidders to fully understand and confirm their ability to provide or utilize vessels equipped with trawl nets meeting these exact specifications prior to submitting proposals.
